Introduction: It is previous reported that HIV populations are deficient in antioxidant system and in vitro HIV replication and depletion of CD4+ T lymphocytes are increased with oxidative stress. The general strategy and combination of micronutrient supplementation as a cost-effective strategy for improving oxidative and nutritional status in HIV infection represent an important complementary deal for treatment in the era of high active antiretroviral therapy. This study assessed the effect of antioxidant extract of Mangifera indica (Vimang) on redox indicators and progression markers of disease. Also toxicological safety was evaluated. Methods: Eighty-two HIV-positive patients were randomized in double-blind clinical trial phase 2 to receive supplements of Vimang or placebo, for 6 months. Plasma antioxidants status (TAS), peroxidation potential (PP) glutathione (GSH), malondialdehyde (MDA), plasma total hydroperoxides (TH), superoxide disumutase (SOD), glutathione peroxidase (GPx), percent of DNA fragmentation (%DNA), CD4, CD38, CD95 lymphocytes subsets and hematological, renal and hepatic indexes were measured at baseline and at 6 months. Results: The supplemented group (n=42) had an increase in plasma TAS (p<0.01), GSH (p<0.05) and GPx (p<0.01) and a reduction in PP (p<0.01), MDA (p<0.01), TH (p<0.01), %DNA (p<0.01) and SOD (p<0.01) when compared with placebo group (n=40). There was also a trend towards a reduction in CD95 receptor (mean ± SD changes over 6 month – 6.12 ± 2.30 vs. – 13.47 ± 3.31 % p=0.08. Conclusions: Supplements of Vimang reduce oxidative stress in HIV with a stabilization of CD4+ T lymphocyte relative count. No significant change (p>0.05) was noted related to micronutrient intake, renal, hematological and hepatic indexes. Vimang antioxidant beneficial effect was found without toxically influences in the 6 months period in HIV studied patients. This is worthy of larger clinical trials; especially both in HIV-positive infected persons who cannot afford antiviral therapies and those with them.
